  1. Let's start building consensus so that we can nurture the ecosystem in a way that will allow us to stick to our core competency while remaining mission critical.
  2. It is correct without glasses on I could not see much of anything more then a couple feet away. I could see 20-20 or pretty close with glasses though. Nobody figured out that I could not see anything until I was around 5 years old. My dad took me to the circus and kept telling me to look at the elephants and so on. LOL I could not see any of it and was more interested in getting some popcorn and a tall orange drink... I remember coming home the first day that I got glasses and being amazed that those blurry green things next to the front door had leaves on them!
  3. I was extremely near sighted with a lot of astigmatism from birth 20-1500 I believe. My corneas were to thin for Lasik so I had PRK done in 2007 which was one of the best things to ever happen to me. I went from thick glasses to almost 20-20 which was awesome. I had about 10 really good years and then my right eye got a little bit far sighted so I had a touch up for that. LOL just my luck right after the touch up I developed cataracts which made me nearsighted. The right eye got pretty bad to the point where I needed a new prescription every couple of months so I had cataract surgery last spring. My doctor told me that because of the PRK it would be a little more difficult to get the vision right, I believe that she said it was about 90%. Anyway the surgery went well and after I was surprised to find out that some kitchen cabinets that I thought had turned yellow were actually still white. Anyway the surgeon got it really close and I only need a slight correction in the right eye which could actually be a result of a bit of a haze that has formed on the back of the new lens. They can go in and wipe the haze off but it is probably not bad enough to warrant doing that at this point. Anyway to make my long story longer my left eye is getting pretty bad now and my astigmatism in that eye shifted by 160 degrees in about 2 months making it really difficult for me to follow the ball. I am constantly asking if anybody saw it. LOL when I golf with my friend who has a bit of macular degeneration it is pretty close to hopeless knowing where the ball went on some of tee shots. I am scheduled to go in and consult with the eye surgeon in a couple of weeks so hopefully I can get my left eye back to a good place with cataract surgery pdq. I did pay extra for laser cataract surgery on the right eye where they cut the slot with a laser and obliterate the old lens with the laser also. This costs a slight bit more but is supposed to heal faster. I was back golfing a week after the surgery so I guess that it healed pretty quickly.
  4. Yes, you are correct on the arm driven aspect of Rinker's upper core swing vs. the body driven aspect of Dr. Kwon's teaching. Of course for lower and mid core Rinker would teach a body driven motion. I do think that even for upper core there are some similarities as far as the back to the target starting down and possibly the way that Kwon wants the arms to release off of the body and fire through the ball. But as you mention there is a very large difference in the teaching. It would be very interesting to see how Mr. Dugan would do being taught by Larry Rinker vs. how he will do being taught by Kwon. Possibly there would not be much difference in ball striking either way and maybe little improvement over the ingrained swing that he had to begin with. Or maybe there will be a large improvement. It would be nice to track the students progress somehow! Edit: One other similarity is that both use ground force to add power. Rinker wants upper core players to jump up through the ball.
  5. I cut open a Bridgestone ball and the crack seems to be a bit different. A sort of center point and fissures moving out from there. Of course the cracks are 3D which makes it a bit hard for me to visualize. Here is a look: I have noticed that some balls tend to crack faster then others. I don't have any hard data on that though... Might be fun to make an automated ball cracking device of some sort maybe a hammer that would pound a ball until it cracked. Would be interesting to test different manufacturers to see which ones are most difficult to crack...
  6. We have had a bit of discussion of Dr. Kwon vs. Larry Rinker / Wright Balance in this thread. Watching Dr. Kwon's videos I am starting to believe that there is not really all that much difference in the students swings from what Larry Rinker might teach. Kwon definitely does not teach the kind of positional stuff the Rinker says his teachers messed him up with when he was on tour. Huge lag and hips way open at impact and so forth. Here is a look at a swing of a Kwon student who I am quite certain would be classified Upper Core by Rinker: Looks a lot like Upper Core, shoulders still closed and hips square. So I think that Rinker and Dr. Kwon would actually have more in common then I might have thought at first glance. LOL Kwon's method is definitely a lot simpler for me to grasp and I don't have to be tested to determine what core I am in order to do the right drills.
  7. Yep. It is like the magic smoke that is inside electrical components. Once the smoke comes out it's all over...
  8. We were actually playing 'winter rules' thru the green during those years that I mentioned the data for which basically meant that I could usually find a nice stalk to sit my ball on in the rough and hit any club that I wanted. We have changed to USGA recommendations for lift clean and place in closely mowed areas only this year which is definitely going to raise scores. It will often be the difference between going for the green and just trying to wedge out to the fairway. The rough is not watered in the summer so it basically disappears but is a broad leaf cabbage in the winter and spring that is difficult to hit out of if you can find your ball in it. Anyway the course plays way longer in the winter and it does not 'balance itself out'. And no I am not complaining as it is what it is and I rather enjoy the challenge LOL.
  9. My course does not drain real well and during the rainy season in the winter and early spring the mud and thick rough is probably a difference of 3 or 4 shots per round for a 10 handicapper. Based on data for the last 10 years my index is typically 2 strokes higher in April then it is in August. Seems like seasonal adjustment might be something for the data crunchers to look at?
  10. Yep definitely get bad numbers on my skytrak on a ball that is ready to go. Often seems to show up as a short slice which is sort of interesting. I don't think that I have ever cracked one in half unless I might have kept hitting a cracked one to see if I could. Don't remember. I will probably cut a few more open to see if the crack always appears to go through the center of the ball. I don't have very many cracked balls right now as I usually throw them away...
  11. Hmmm, not sure if this is the right place for this post. Or if there is a right place? I hit a lot of balls on my simulator setup and eventually every ball will crack. I have noticed that a ball that is getting ready to crack on the outside will feel really bad on impact for a while before the crack shows up so I figured that the ball cracks on the inside first. Anyway I decided to cut open a cracked ball to find out what the crack looks like on the inside. Here is the cracked ball, a Mizuno RB Tour but it could be any ball: I cut it open using a PVC pipe cutter: Here is a look at the crack on both halves: Looks like the crack goes right to the center of the ball. Here I shoved a screw driver into the crack: LOL most boring post ever? One thing for sure is that if you play a ball for too long or maybe one that you picked out of the range bucket and you cannot hit a solid shot with it there could be a reason other then your swing!
  12. I knew a guy years ago who had a small golf shop and he had an interesting loft / lie machine that he said was designed by a mechanical engineer who approached the problem with no knowledge of conventional bending machines. This particular machine operated with a motor and and a lead screw that could be set to bend to whatever loft or lie desired. This was back in the mid nineties so my memory of the machine is a bit fuzzy but I do recall being impressed with how easy it was to measure and bend clubs. I wonder if anyone here knows anything about that machine?
  13. As I mentioned before he was talking about the learning process not the importance of the movement. Obviously if the wrists are not able to move correctly because of a bad grip or whatever then the correct body movement is not going to produce straight shots. I understand Kwon to say that if the body is moving correctly then getting the wrist movement correct is a simple matter. This is why imho Dr. Kwon spends most of the training time with the student swinging the club (or rope for that matter) with no ball being hit. Get the body motion correct and the rest of it is 5% or something like that. Things like the swing plane and so on that others spend a lot of time training simply come naturally with the drills. He mentions swing plane learned in this matter while doing the rope drill. I have never had lessons of this nature and have always hit balls with the instructor watching and making suggestions / corrections possibly with a few drills sprinkled in. I think that Kwon's approach is a better way to go at it.
  14. Parallax. The club to lead arm is probably right around 90 degrees in both pictures. If you don't believe me you can easily see the effect standing in front of a mirror and holding a club up and tilting it around to see how sharp the angle can appear. The only way to see the angle correctly is to have the camera perpendicular to the swing plane. The flatter the plane the more the effect from face on.
  15. Modular design, made in the US and milled instead of cast or forged. Okay I like that. I have seen these in the past so I guess that they have been around for a while? They lost me when they said this though: This might be the most radical thing. Unlike other irons, MOD™/1 IRONS don’t need to be adjusted to a specific lie angle. Whether you prefer 2-degrees flat or a more upright lie angle, you’ll achieve peak performance through the dynamic shaping of sole and flange profiles. One Caveat: For golfers that prefer flatter lie angles (more than 2 degrees), we offer a special Hosel. LOL lie angle is just a bit more involved then that and if the angle is off then the shots are not going to fly straight regardless of sole and flange profile. When I first looked at the clubs I assumed that lie angle was adjustable. Unlike most everyone else who has posted on this thread so far I kind of like the way the clubs look and I would have no problem putting them in my bag as far as that goes. I wonder if anyone has ever seen these being played out in the world?
  16. Here is data collection for Grant Waite:
  17. Here is what I remember for my subscription to AMG+: In AMG+ I learned that the average tour pro's spine tilts towards the target 2 or 3 degrees around lead arm parallel to the ground in the backswing. One of their pros tilts 5 or 6 degrees of tilt which they believe is good. The way I see it is that this has to happen if there is an initial shift into the trail leg and the head stays still. AMG does mention something to the effect that you cannot necessarily see the tilt on video unless you know what you are looking for. They measure spine tilt on the GEARS system or whatever system that they are using now. The shift back to the lead foot starts around the time of max lean or maybe slightly before that as the entire spine is moving towards the target and the lean goes away when the hips shift forward. This movement is what I see in Kwon's teaching. It is built into the up and down and back and through. It is all one unified movement start to finish which is a good thing.
  18. I had to look up Active Release Technique. It sounds a bit like SOMAX / Bob Pritchard sort of stuff? And no it is not similar to MAT at least as far as I can tell. MAT is a process of testing specific muscles that are not activating and getting them working again.
  19. Looks like little bit of re-centering move or reverse tilt same as I learned from AMG+. It seems to work and is something that tour pros do according to AMG. Some here may not like it but there it is!
  20. That is a pretty detailed investigation that you have made. I would say that you seem pretty close to how it works based on what I know from a patients perspective. I have used a foam roller for many years and that did or does help a lot especially with the knots that I used to get in my shoulders all the time. For me as I have described elsewhere MAT was a big improvement over simply foam rolling. At this point I know enough of MAT from the sessions that I have had to do a slight bit of self treatment which I think sometimes helps a bit and I also have a number of isometric sort of exercises to do that are definitely beneficial. Proving that MAT works is difficult. For instance if I had gone to a doctor prior to MAT for my back pain the doctor might have prescribed pain relievers and physical therapy or whatever. Actually I did go through such treatment years ago after a work related back injury. Those things helped some but I still had chronic pain for a number of years. Anyway suppose that at some point after the MAT treatments I go back to the doctor and try to tell the MAT story the doctor will be skeptical and probably say that I would have gotten better anyway and that MAT is a placebo. It is a really hard battle for MAT practitioners to win LOL nobody believes that the patients are actually living better lives because of MAT and there is no way to prove that they would have needed surgery or whatever without it... I wonder if you might consider getting a one hour treatment to see what it is all about?
  21. That is probably why Kwon seems to teach the motion mostly with no ball present. I think that if the motion is learned and ingrained then correcting the grip is not such a big deal.
  22. I understood Kwon to mean that 95% of learning the swing is getting the body motion. The wrist motion is not a problem and might require a slight adjustment to straighten out ball flight providing that the body motion is correct.
  23. Wow! I thought that it was common knowledge that the wrists transmit the power to the club from the body and don't do anything active during a good swing. Sounds like some have a different idea?
  24. I think that I twirl every club when I put it back in the bag. I have been doing that for as long as I can remember. Nobody ever says anything about it so maybe it is not very noticeable...
  25. LOL I am thinking that the air in the shaft must have some effect... If we filled the shaft with spray foam for instance... Of course that would change the weight and flex a lot I suppose... Maybe helium would do it! Or pure nitrogen sealed shafts at 100 psi! They do claim benefits to filling road tires with nitrogen...
